Specification of Letters Patent. Application filed December l9 1904. Serial No. 237,457.

Patented Dec. 18, 1906.

- To all whom it may concern:

Be it known that I, WILLIAM E. How, a citizen of the United States, residing at New York, in-the county of New York and State of New York, have invented certain new and useful lmprovements in SadIrons, of which the following is a specification.

This invention relates to improvements in sad irons having a combustion chamber formed within its interior, wherein a suitable material, such as charcoal, is burned for the purpose of heating the iron to a tem erature which will enable it to be used for al ironing purposes continuously throughout a whole ays work, if necessary, without the trouble and delay of heating theiron on a stove.

I .It is well known that the weekly ironing is one of the most arduous tasks which confronts the housekeeper, particularly during the hot summer weather, when the person pgrforming those operations with the wellown solidirons is required to labor in the -vicinity of a hot stove on which to heat the r-"llOIIS; but with an iron of the so-called selff'esfheating type, which includes my invention,

' I the ironing may be done in some cool retreat,

even under the shade of a tree where the erson performing the labor can be fanne by every breeze that blows instead of being op- 0 pressed to the verge of prostration between the four walls of a heated room. Under such cbfnditions as are made possible by inventions' -like this the small charcoal fire re quired. within the iron to heat it will be inappreciable to the operator or ironer.

An important ob ect of my invention is to provide means for retaining the position of the movable door when the latter is elevated to allow a free access of air to the grate-bar,

0 which forms a flue under the bed of charcoal.

Another object of my invention is to pro- ;bethoroughly efii; bleathat-wcan beiproducedfi H 'not makethe irontcum p m I oi'anoonvenient.f- I

Fig. 2 is a longitudinal vertical section on the line 2 2 of Fig. 1, showing the door at the end in elevated or open position. Fig. 3 is a detail in vertical section of the rear end of the iron on the same plane as the section in Fig.

Fig. 4 is a detail in perspective of the grate-bar of the iron. Fig. 5 1s a detail in perspective showing the body of the iron with the end door and the top of the iron removed, and Fig. 6 is a ers 'ective of the iron turned on its side with a iiilting device applied to the latter and in operative position. Fig. 7 is a view in transverse vertlcal section of my iron.

Like characters of reference indicate like parts throughout the several views of the drawings.

'7 is the body of the iron, which is of usual shape and size and is made hollow to form a chamber which is open at the rear end of the iron. This opening has the flanges 8 at each I side thereof to form guides to retain and di- I rect thesliding door or gate 9. Both sides of this body have air-holes 10, and located with-1 in the body against the side walls thereof are the sliding damper-plates 11, one on each side of th Iron, which tl'G connected by the 8 bridgelate 40, whereby said damper-plates 11 will ave simultaneous movement. The said plates 11 have suitable openings which are brought into register with the openings in the sides of the iron more or less completely by the longitudinal movement of said plates.

12 is the top of the iron,having achimney 13 for the esoa e of the waste products of combustion and for the complete ventilation or draft of the iron. This chimney has the 0 damper 14 for the purpose of regulating the draft. At the opposite end of said top from the chimney is the standard 15, which forms one of'the connections for a handle 16, the opposite end of said handle being supported by attachment to the wall of chimney 13. A heat-deflector 17 is interposed between the The top 12 as'tened by sc'rws it gh20 1isvasheetem dining fastened-by screws 1'9,'ab oye mentioned. This lining is held by the'ribs 21 away'from the outer side walls of the iron, so as to produce air-passages at the sides of the combustionchamber. This lining terminates at a suitable distance above the bottom of the combustion-chamber to allow for the discharge of air underit into the iron from the passage- 1 10 ways above referred to.

22 is a lever which rests upon the top 12 of means of the screw 23. The.to,p of the iron has a longitudinal slot 24, through which a rivet 25 passes to connect the lever with the cross-bar 40, connecting the side dampers 11'. The free end of the lever is provided with a knob for the convenient shifting of the lever by ressure with the thumb of the o erator to thereb change the position of the p ates 1 1 and regulate the supply of air through the sides of the iron.

Located within the iron upon the bottom thereof is a false bottom 26 with air-passages between it and the real bottom of the iron. Preferably there will be three passage-ways occupying practically the whole width of the bottom adjacent to the door, but the two outside ways will terminate at about onefourth of the length of the combustionchamber in from the door, while the middle passage will extend nearly the entire length of the interior of the iron. These assages 0 en at their ends into the com ustionc amber and they have additional top openings 27 thereto. The reason that the outer assages do not extend as far into the com- Eustion-chamber as the middle one is that they keep the charcoal from contact with the bottom of the iron to such an extent as to interfere with the heating of the latter.

The to-and-fro movement of the iron as used will cause an air circulation through it if proper openings are rovided; but as a rapid movement woul force more air through the same openings than a slow movement it is necessary to provide means for regulating the size of the air-inlets.

In my invention I make the door 9 hollow and close 'the chamber thus formed with an inside plate 28, having a number of evenlydistributed 0 enings 29 to distribute the air equally to the whole mass of fuel. The outer wall of the chamber has the air-o enings 30 closed by the sliding damper 31, aving the usual openings, whereby the size of the air-inlets to said chamber may be regulated. At certain times, as when the charcoal fire in the iron burns too low or in starting the fireat the beginning of the operation of ironing, it is desirable to raise the door into the position shown in Fig. 2 with the lower end of the door rest upon the hollow ia sabottenigrgmia o1" flange 47 next to the end, and the door has a:- bottomfl'ange to engage the flange 47-, thereby forming a lock, which .will prevent th ea'sy displacement of the door when thus placed in elevated position. As the door in order to be tilted into the, position shown in Fig. 2 must fit loosely withm the flanged end of the body 7 it will be liable to displacement by the jar occasioned by the movement of the iron from the position shown in Fig. 2, and in order to hold it securely against such displacement and to cause it to' assume this elatter-ha the-- oblique position when raised I provide the spring 32, which has its upper end fastened, by means of a screw 33, to the standard 15 and has the angular portion 34 bent out, so as to stand in the path of the door when the latter is raised and by pressure against the raised upper end of the door to press said upper end in an outward direction against t tops of flanges 8 as a fulcrum, thereby. causing the lower end of the door to move inwardly to a position where its bottom flange will lie inside of flange 47on the grate-bar. The standard 15 has a socket 36 to receive the end of s ring 32 when the latter is pressed in by t e action of the door, as'above described, and in order to facilitate the compression of the spring by contact with it of the door when the latter is raised I form its lower end into the oblique member 37.

Havin thus fully described my invention, what I c aim as new, and wish to secure by Letters Patent, is

1. In a hollow sad-iron in which charcoal is burned to heat it, a false bottom for said iron having under side air-passages, and a transverse upwardly-projected rib or flange at its outer end, a vertically-slidin door capable of swinging inwardly at its ower end to rest upon saidfalse bottom, and a spring to press against the door and swing itsinner' end inwardly when the door is raised.

2. A hollow sad-iron having hollow walls with damper-regulated openings in said hollow walls, a false bottom for said iron having air-passages with top and end openings into the combustionchamber of the iron, and said false bottom having an upwardlyrojected rib at its outer end, a vertically-sliding door capable of swinging in at its lower end to rest upon the false bottom when the door is sufficiently elevated, and a spring secured to the iron and adapted to press against the door to swing the lower end of the latter inwardly when the door is raised.

3. A hollow sad-iron having a combustion chamber in'which charcoal is burned to heat it, said chamber having air-passages in its walls and dampers to regulate the air-passages therethrough, said iron having a vertical standard at its rear end, :a false-bottom for said'iron having air-passages, with openingsinto the combustion-chamber, vertg 1,1 flanges atthe rear -openendofthe iron, a sliding door secured by said flanges and adapted when raised above the false bottom to swing inwardly at its lower end and engage the end of said false bottom, and a spring fastened to said standard and having its free end in the path of the door when the latter is raised, said spring being adapted to press the upper end of the door out thereby causing its inner end to swing inwardly into engagement with said false bottom.

4. In a sad-iron, a hollow body in which charcoal is burned to heat it, said iron having a chimney at its front end and a standard at its rear end, a handle su ported by the chimney and standard, sai standard having a socket, a spring fastened at its upper end to .the standard and having an angular outwardly-projected bend at its lower end terminating with an oblique portion which enters the socket .when the spring is pressed toward the standard, flanges at the rear open endof the sad-iron, a door held by said flanges and adjustable vertically between the flanges and the other portions of the iron and adapted to be pressed outwardly at its upper end by said spring whereby its lower end will be made to swlng inwardly into engager 5 ment with said false bottom when the door is raised.

In witness whereof I have hereunto set my hand and sea], at Indianapolis, Indiana, this 2d day of December, A. D. 1904.
